Description
Omnispace Agora Project through 26.10.0 contains a predictable token generation vulnerability that allows unauthenticated attackers to access private calendar data by exploiting a missing dateCrea value that causes the md5Id token to collapse to md5(calendarId.userId), both small enumerable integers. Attackers can compute valid tokens and request the misc&action=DisplayIcal endpoint with a forged md5Id to read any user's private calendar events without authentication.
